Focus and Development 

Writers often mention or list ideas without fully developing them in their early drafts. Working in this way can be very helpful for generating ideas. However, you must check your draft for such points and consider how to extend them as you revise.

Each paragraph should have a central idea that is developed in some way related to the overall context of the paper. As you review each paragraph for focus and development, also check that you have appropriately acknowledged any sources you used for the ideas in the paragraph.
